3 关于to do 的逻辑主语

我看到了几种说法:

1. To do, svo. 句型中的 Inf的逻辑主语与句子主语可一致也可不一致:

例如:To made stereo effects, two recordings are made the some performances.

2.不定式放句首时,逻辑主语与句子主语要一致。

To save money, he has tried every means.

To save money, every means has been tried. ×

上述两种说法矛盾。不知道真实的情况是如何呢?

另外:Therefore to increase the yield of the targeted reaction products, many factors are taken into consideration.这句话语法对不对呢?

你的问题句属于出现垂悬修饰语(dangling modifiers)的错误。根据语法规则,主句主语应该和修饰语中的主语一致才正确。根据《牛津英语语法指南》第四版115(4)词条的解释,对于垂悬修饰语,目前已经接受的是主句为形式主语或there be结构,或垂悬部分为习惯用语的情形,请看该书例句:

1. Being French, it's surprising that she's such a terrible cook.

2. Having so little time, there was not much that I could do.

3. Considering everything it wasn't a bad year.

以上用法都是正确的。

你的句子属于不定式结构,属于尚未认可的用法。国外一些网站的语法教学页面也有讲解,如:

Example

To investigate the relationship, a series of experiments were designed. (Incorrect)

 (Who is going to investigate? Implied subject = we/researchers; grammatical subject = a series)

 Correction:

We designed a series of experiments to investigate the relationship.
